Figures 65-70View Plate VIII (larva)

Material. 5♂, 2♀ (adults), 1♂ larva (ultimate instar), Base CampGoogleMaps  .

Larva. Small, dark, with some yellow spots on the pterothorax. Head much broader than long, with almost straight occipital margin ( Fig. 65View Plate VIII), Antennae as illustrated ( Fig. 66View Plate VIII); segment 6 the longest, dark basally; apical segment spindle-shaped with pointed tip. Hinge of labium reaching second coxae. Labium as in Figs. 67-68View Plate VIII. Hind margin of pronotum laterally somewhat protru· ding, and spinous. Legs moderately long, femora with two dark rings. Wing sheaths reaching to end of abdominal segment 5. Abdomen with dorsal hooks on segments 3-9 and with long lateral spines on segments 8 and 9 ( Fig. 69View Plate VIII). Anal pyramid as in Fig. 70View Plate VIII.

Measurements. Total length (excl. lateral spi· nes) 9.5; maximum width of head across compound eyes 3.0; hind femur 3.0; hind tibia 3.6.

Remarks. The larva was found between leaf lit. ter in the pool described under Acanthagrion apicale  (see above) Here, adult males as well as an ovipositing female were observed. The larva when disturbed feigns death. The unique specimen found was reared to emergence, but died during transformation. Therefore it can be associated with Fylgia  kirby only by supposition. Ho. wever, small size and peculiar features practically exclude any other genus.
